Tom Thumb Piano

I just acquired a piano called a Tom Thumb manufactured by the Milton Piano
Company in New York. Apparently, the company was a part of Kohler and
Campbell during the early part of the 20th century. This instrument is a
miniature version (fewer keys and smaller) of a normal vertical instrument,
but with a full-sized action.

Can any of you give me additional information on this type of piano or on
the manufacturer?
